Limitations of CPM (Critical Path Methodology)

Know the Limitations of Critical Path Methodology
Critical Path Methodology (CPM) was developed by DuPont over 50 years ago as an effective method to identify activities with no tolerance for delay. You can use the Gantt Chart Wizard function to display the critical path in Microsoft Project. One significant limitation with the Critical Path Method is that it doesn't account for resource constraints, only task dependencies. Project managers who are dealing with limited resources often find that not all projects can be managed to the critical path schedule. Incorporating the Resource Leveling feature can help a project manager identify resource bottlenecks in addition to the critical path. Using the Leveling Delay column and the critical path helps to pinpoint which resources and tasks are the ones to focus on first when optimizing the schedule.
